Overview

Mozilla is partnered with a number of carriers and OEMs in the development of Firefox OS, to bring accessible devices to emerging mobile markets in 2013.

The Firefox OS Developer Preview is a release in collaboration with Telefonica and Geeksphone for the following devices:

Pull the utility tray down from the top of your phone for quick access to WiFi, Data, Bluetooth, Airplane mode & Settings.

The Firefox Marketplace offers you two ways to find apps, you can browse for new apps or you can search for them.

Search

If you want to search for the name of the App that you are looking for you can:

From the home screen, tap on the magnifying glass
and write your search keywords.

In any other page, type your search keywords at the top of the screen.

The search function allows you to explore apps using their name or specific keywords. For example, if you search for "game" you can find the list of all the available games.

Browsing

If you decide to browse the Firefox Marketplace to see what's available, you can do so by selecting one of the 6 categories at the bottom of the Home page. Each of them will show you a list of apps that you can download.

You can reduce the selection of apps by taping on the "Filter" button and selecting the topics that you are more interested in.

It possible to customize the view to show screenshots of the apps or show more apps without scrolling. To do so, press the
button.

Privacy and security settings

It's helpful for Mozilla's engineers to be able to measure how Firefox for Android behaves in the real world. The Telemetry feature provides this capability by sending them performance and usage information. As you use Firefox, Telemetry measures and collects non-personal information, such as memory consumption, responsiveness timing and feature usage. It then sends this information to Mozilla on a daily basis and we use it to make Firefox better for you.

Firefox also has a Crash Reporter feature that warns you when Firefox closes unexpectedly, and allows you to send this information so the engineers can make Firefox more stable and secure.

For more about what kind of information is collected and how it's used, see our privacy policy.
